RELEASE NOTES

Release notes 1.81a

Driver for all supported cards. Includes 1825 audio drivers for Windows 10. Unlike previous releases, the 1825 audio driver will only work in Windows 10.

Driver changes:

  • Windows 10: Updated audio driver to 1825 (built date: 22 ‎June ‎2016, made by C-Media).
  • Updated C-Media Panel.

Other notes:

  • Replaced C-Media driver uninstaller with UNi Xonar driver cleaner.

Rev. 2 changes:

  • Added support for STXII cards in Asus Audio Center, cards will be detected as STX by Asus Audio Center but feature wise almost everything should be there.

Known issues:

  • 1825 audio drivers have an issue when the audio card is uninstalled, disabled or the drivers are overwritten, resulting in a system crash. In order to avoid the uninstall system crash I’ve come up with a workaround  that’s presented below
  • Asus Audio Center: GX button is no longer showing. It has to do with 1825 audio drivers and there may be a reason why C-Media removed it. I’m not sure if it’s worth it to bring the GX on/off control back.
  • STX II:  Asus Audio Center is missing the gain 16/32 ohms for headset.

Possible issues:

  • STX II: XonarSwitch might not work. Need more feedback on this.
  • Audio playback through headphones and SPDIF at the same time isn’t possible anymore. Original report. Need more confirmations.
  • DSX & probably other cards: DTS Connect with 5.1 speakers does not work. Original report. Need more confirmations.
  • There are reports that the sound quality of these audio drivers is different. RightMarkAudio tests that I’ve made didn’t show any significant differences between v1.81a and v1.80a.
  • The 1825 audio driver may have higher DPC latency than previous drivers. Original report. The tests that I’ve made didn’t show any difference in DPC Latency between v1.81a, v1.80a and v1.80b drivers. Maybe it’s has to do with the settings that are being used.  My test where done with 2.0 analog output.

How to uninstall 1825 v1.81 drivers: In order to avoid a system crash while uninstalling 1825 drivers you will need to play an audio file before proceeding with the uninstall process. Restart system after the uninstall process is done.

 

Release notes 1.80

UNi Xonar installer changes:

  • Added DPI interface scaling to the installer.
  • Added card autodetection and if the audio card is not detected it will show an error message with possible reasons for that.
  • Improved driver cleaning. It uninstalls all copies of the Xonar/C-media CMI8788 drivers that are present in the Windows driver repository. By installing drivers with “Run driver cleaning” option you won’t be able to use “Roll Back Driver” option for the audio card in Device Manager.
  • Changed the driver installation procedure. Added a fail safe driver installer that should help in those cases where you were required to manually install the audio driver or install it in safe mode. Silent installation is always on and its user option has been removed. If standard driver installation gets stuck (does not finish after 100 sec) it is automatically closed. If standard driver installer fails to install the drivers then an alternate driver installer is launched. If that fails too, you will get notified by the installer that driver installation failed.

Driver changes:

  • Windows XP: Added support for other CMI8788 cards.
  • Xonar DG, DGX, DG SI: Front Panel jack detection should now work if it did with the original drivers.
  • Fixed GX not being turned off by default in “Normal” configuration for the following cards Xonar D2, D2X, DG, DGX and DG SI.

Rev. 2 changes:

  • Improved and fixed some problems with the new driver installation procedure.
  • Added different messages based on why installation failed.
  • Fixed “Front Panel Microphone” not working by default.

Rev. 3 changes:

  • Increased the delay between driver cleaning and driver installation procedures. Might help in some installation failing cases.
  • Fixed the “Warning: Windows running in Test Mode or with Disable Driver Signature Enforcement is required!” message not showing up if needed in combination with the detected audio card.

The 1.80 drivers come in two variants:

  • 1.80a “Standard”

Driver for all supported cards. Replacement for 1.75a driver. Includes 1816 audio drivers for Win XP and 1823 audio drivers for Windows Vista/7/8/8.1/10.

Driver changes:

  • Windows Vista/7/8/8.1/10: Updated audio driver to 1823 (built date: 2 Jun 2015, made by C-Media).
  • Includes updated driver installer, ASUS Audio Center and C-Media Panel.

Other notes:

  • 1823 audio drivers are the first drivers released for Windows 10 by ASUS/C-Media. Whether they perform any better than 1822 or STXII 11.5 drivers remains to be seen.
  • Xonar STX II cards: Drivers work with STXII cards but the changing audio settings may not work with ASUS Audio Center and only with C-Media Panel. Installation on Windows Vista/7/8.1/10 x64 requires Windows running in Test Mode or with “Disable Driver Signature Enforcement” option.

Known issues:

  • STXII: Asus Audio Center does not work. You need to download this patched version and copy paste it over “C:\Program Files\UNi Xonar Audio\Customapp\”.

Possible issues:

  • Microphone stops working if running specific programs. If you run into this issue please report it in a reply to the original report. If you run into the issue you can switch to v1.75a drivers or connect the microphone to the onboard audio card microphone input.
  • WASAPI playback issues might occur with some soundcards
  • Occasionally when waking PC up from sleep the Xonar card does not output any sound.
  • Drivers might stop installing on Windows 10. Try 1.75a, 1.80b or 1.81a instead.
  • Windows 10 Creators Update: Windows would not boot after these drivers where installed. If you run into this problem you have to boot Windows in Safe Mode and remove the audio drivers. Original report. I could not reproduce the issue.
  • 1.80b “STXII”

Driver maily for STX II and  STX II 7.1 cards. It does work for the other UNi Xonar supported cards too. Replacement for 1.75b driver. Includes STX II version 11.5 audio drivers (built date: 18 Feb 2014, made by C-Media).

Driver changes:

  • Includes updated ASIO (2.0.0.14), driver installer, ASUS Audio Center and C-Media Panel.
  • Windows XP: Drivers now work for all UNi Xonar supported cards. These were not working with 1.75b drivers.

Other notes:

Rev. 2 changes:

  • Fixed “Asus Audio Center” not working properly and getting replaced by C-Media Panel when installing with “Normal – Asus Audio Center” configuration.

Rev. 3 changes:

  • Fixed some installation issues when drivers were installed on STXII cards (like missing driver uninstall entry in Programs and Features,  incorrect C-media panel name).
  • Fixed a bug where optimal card configuration was not being applied if the drivers were installed without the “Re-enable stereo upmix” option.

Possible issues:

  • Microphone stops working occasionally or when changing audio playback settings (DS->WASAPI). If you run into this issue please report it in a reply to this comment. If you frequently run into the issue you could try v1.75a drivers if possible or connect the microphone to the onboard audio card microphone input.

 

Release notes 1.75

UNi Xonar Installer changes:

  • Various changes and improvements done to the UNi Xonar installer.
  • Added warning message if installing the drivers would require Test Mode.
  • XonarSwitch is now automatically closed before installing the audio drivers.
  • Improved “Apply addons” function. Included .inf files from the drivers can now be dynamically altered. Documentation can be read here. Applying new 1.75 compatible versions of addons (like DHT4) will display the proper audio driver version now and users could now choose which addons they want to install once these are added to the Uni Xonar installer location.

Rev. 3 changes:

  • Fixed GX is not being turned off by default in Normal configuration for the following cards Xonar D2, D2X, DG, DGX, DG SI.

The 1.75 drivers come in two variants:

  • 1.75a “Standard”

Driver for previously supported cards. Same audio drivers as those in 1.72 (1816 for Win XP, 1822 for Windows Vista/7/8/8.1/10).

Rev.2 changes:

  • Fixed ASUS and C-Media Panels not working in Win XP.
  • Includes updated driver installer and C-Media Panel.

Known issues:

  • The installer is showing “Warning: Test mode to be enabled!” message by mistake if Xonar Xense selected as card.

Possible issues:

  • Missing Dolby Pro-Logic IIx options from C-media Panel. If you have this issue, you can use the “C-media Panel v1.62” installer addon or install v1.72 drivers.
  • 1.75b “STXII”

Driver mainly for STX II and  STX II 7.1 cards. It also works with UNi Xonar previously supported cards.

Rev.2 changes:

  • Fixed issue where installer did not apply the correct audio settings (e.g. to fix surround echo). Anyone who installed the previous 1.75b drivers should install the 1.75b rev.2.

Driver changes:

  • Includes updated ASIO (2.0.0.13) , ASUS Audio Center and C-Media Panel.
  • Includes STX II version 11.5  audio drivers (created on 18 Feb 2014).

Other notes:

  • These drivers will work with the previously supported Xonar cards on Win Vista/7/8.1/10 but may require that you enable Windows Test Mode on 64 bit OS.
  • These drivers do not work for the other Xonar cards on Windows XP.

Known issues:

  • ASIO in 64 bit mode does not work. The cause of this issue is the 64 bit asio  dll file from the original STXII drivers.

Driver changes:

  • Updated audio driver to version 1822 for Windows Vista/7/8/8.1. Still using 1816 for Windows XP.

Other notes:

  • New icon for UNi Xonar installer. Thanks to propheticus for his contribution.
  • ASUS Audio Center and C-Media Panel tray icons now have higher resolution icons. Useful for >100% DPI settings.

Known issues:

  • GX is not being turned off by default in Normal configuration for the following cards Xonar D2, D2X, DG, DGX, DG SI.

Release notes 1.71

Driver changes:

  • Updated audio driver to 1821 for Windows Vista/7/8  and 1816 for Windows XP.

UNi Xonar Installer changes:

  • Fixed some issues with Driver cleaning module
  • Improved and fixed some potential issues with UNi Xonar Installer

  • In some cases,  WASAPI exclusive playback is interrupted by playback from other audio applications. More details here.  Fix: If you don’t use S/PDIF, disable Digital Output from Control panel->Sound. It’s confirmed that the audio drivers included in 1.70 don’t have this issue.

Notes about Windows 10 compatibility (updated 10 May 2017)

UNi Xonar drivers above v1.64 will work in Windows 10 but since the audio drivers are not yet made specifically for Windows 10 there could be some issues that you could run into depending on audio settings used. Different drivers could work differently so if you encounter any issues try installing the other UNi Xonar versions.

Apart from driver issues there could be issues solely from Windows 10 sound system that would be fixed with future Windows updates. There is also a small chance that some things could break with future Windows updates.

Update 20 Apr 2017, 10 May 2017: Windows 10 Creators Update (build 1703) reported issues so far are:

Your feedback is welcome.  For those of you who run into severe problems after the Creators Update build upgrade you could roll back to the previous Windows 10 build (#1, #2). If that is no longer possible you can download an older Windows 10 build from here and install it without a internet connection present.

To prevent Windows 10 upgrade to Creators Update you need to either disable “Windows Update” service from Control Panel->Administrative Tools->Services or disable the Creators Update update with Wushowhide tool (guide on how to use it).

Update 30 Aug 2016: Thank you for the feedback so far. Based on the feedback received there shouldn’t be any problems installing the drivers on Windows 10 Anniversary Update (build 1607) whether it’s an upgrade or a new installation. One user reported that audio card was recognized only when installing the drivers when booting with Disable Driver Signature Enforcement option. Apart from drivers installation aspect, this new Windows build brings new problems for some users like the following reported ones: crackling or loud popping sound in the speakers, audio card not being detected sometimes or disappearing in Windows and 5.1 analog not working. For those of you who started having problems only after the Anniversary build upgrade you could roll back to a previous Windows 10 build (#1, #2). If that is not possible you can download a older Windows 10 build from here and install it without a internet connection present. To prevent upgrading to build 1607 you need to disable “Windows Update” service from Control Panel->Administrative Tools->Services.

Update 3 Aug 2016: Microsoft made changes to driver signature policy with the Windows 10 Anniversary Update (1607) that could make the Xonar drivers not working/installing anymore. There are some exceptions from this driver signature enforcement. At the moment it’s unclear to me if installing the drivers in Test Mode or with Disable Driver Signature Enforcement still works. I’m interested in hearing you experience under this discussion thread.

Update 28 Nov 2015: The Windows 10 Threshold 2 update does not seem to fix many of the sound issues that where present so far and it may introduce new ones. In my opinion Windows 10 is a very buggy OS, the only things working fine are the spying of its users(#1, #2) and the periodic removal of user preferences and programs(#1, #2, #3, #4).

Update 19 Oct 2015: The audio fixes from Insider Previews >= 10547 will probably be included in the upcoming “Threshold 2” update that will be released around November 2015.

Update 1 Oct 2015: The Windows 10 development team is fixing some audio issues with Windows 10. The fixes where made available for testing starting with Windows 10 Insider Preview build 10547.

 

100% compatible drivers when?

Because of the very slow development of the audio drivers by C-Media and the long time it takes for C-Media partners (ASUS and HTOmega) to release the new drivers it may take a while before we have a 100% compatible driver for Windows 10.  If we are lucky we will have new audio drivers in 2-3 months after Windows 10 RTM launch. As soon as new audio drivers became available I will release a new UNi Xonar drivers package.

  • Update 25 Jan 2017: 1825 audio drivers for Windows 10 are available. These are the first audio drivers that only work on Windows 10. Hopefully they will perform better than those that supported also Windows 7 and Windows 8.1.
  • Update 01 Oct 2015: 1823 audio drivers are the first drivers released for Windows 10 by ASUS/C-Media. Whether they perform any better than 1822 or STXII 11.5 drivers remains to be seen.

About Chrome stutter issues on sites like YouTube. (27 Aug 2015)

  • Update 27 Aug 2015: The stutter issues on youtube are  fixed with the latest Chrome build released on 20 Aug 2015 (v 44.0.2403.157). Reports indicate that stutter issues are still happening for videos on other websites (eg. daily motion, facebook, instagram).
  • Update 7 Aug 2015: After some testing and some reading it seems that the stuttering issues are not related to the UNi Xonar drivers. I’ve got the same behavior with Realtek’s onboard audio and from what it looked liked. My guess the issue is caused either by Windows 10 or Chrome.

There is a Chromium issue opened here.

Here are some things you could try:

  • Change Chrome audio buffer size.
  • Change/keep sample rate to 44.1 kHz both in the audio panel and Windows Volume->Playback devices->(…) Audio Device Proprieties -> Advanced -> Default Format.
  • Change sample rates back and forward a couple of times.

    My xonar stx has lost the ability to do anything but 2ch stereo since recent windows updates. Its an older card and none of the drivers seem to help. Is there still support for this card in the future, anyone have a functional stx?

      Actually 1.80a r3 is working for me. Not perfect but movies are playing in proper 5.1 now. Going to play around more with all of these great drivers and addons. Thanks for the hard work guys. To bad Asus doesn’t work harder on their drivers because there are probably a lot if people in my situation. It took me a few days of tinkering and searching to find this site.

    Please add restart card function to the driver pack. Sometimes my Xonar DX stops playing sound in right chanel and I’ve had to restart computer, to restart the card.

    Sorry if i don’t read through 195 page.

    Is it possible to run two Xonar in one PC?
    I have a Essence ST and got a HDAV1.3 today.

    • CarvedInside    27 Jul 2017 @ 20:51   

      I think they should work. Read FAQ Q&A 22 on how to change settings for each card.

      • MrGlasspoole    28 Jul 2017 @ 15:47   

        First i did install the HDAV with just C-Media Panel – that worked. Then i plugged the ST in but had only the yellow exclamation mark in the device manager.
        So i did install the driver again but still only exclamation mark. It does not work.
        By the way: XonarSwitch says the HDAV is not supported.

        • CarvedInside    29 Jul 2017 @ 02:15   

          What it says under “Device status” in ASUS Xonar ST Proprieties from Device Manager? Have you tried without having the HDAV card plugged?
          Which drivers have you installed?

          Yeah, forgot that XonarSwitch does not currently support HDAV cards. You could also control settings for each card by disabling one in device manager and launching ASUS/C-media Panel.

            I did not check what the status was. I tried v1.80a and v1.80b. You mean taking out the HDAV, install the ST and then putting back the HDAV?

            Thanks for trying to help but i have bigger problem to solve now 🙁
            I was looking a long time for a H6 board for my Essence ST.
            Last week one showed up – a HDAV1.3 Deluxe.
            So i bought the whole package because i was searching a H6 since a long time.

            Now the problem is that i don’t get sound from my ST after i plug in the H6.
            The left and right speaker outputs stop working.
            I tried UNi v1.80a, v1.80b, v1.75a and the Asus v8.1.8.1822 Beta driver.
            I tried installing the driver with and without the “Re-enable stereo upmix to 4, 5.1 & 7.1” option.

            Then to make sure the H6 is ok i did install the HDAV + H6 in my HTPC and it works.
            If the H6 works with the HDAV i guess it is not defective?
            But my ST analog output only works if i unplug the H6…

    Is there support for zero latency mic monitoring in windows 10? (see: http://i59.tinypic.com/2ijpxea.jpg)

    Using the ‘monitoring’ feature in the mic or in the asus panel has about a 100ms delay.

      I think you linked the wrong picture.
      I don’t know about this. Are you using the ASUS drivers or the UNi Xonar drivers? How do you measure the mic monitor delay?

        Sorry, should have clarified. I want my control panel to look like that picture. In the options for my speaker I only see the volume, no extra devices. This is what mine looks like: http://i.imgur.com/95e3O1l.png

        I initially had the ASUS drivers installed, then installed the UNI drivers afterwards. I installed with ‘low latency’ selected, on version v1.80a-r3

          Can’t help you with the changing what’s being showed in Speaker Proprieties panel.

          About the delay with mic monitor, did you had this problem when you had the ASUS drivers? If it’s possible to tell me how did you measure the delay?

            Yeah the delay was the same with the ASUS drivers and after I installed the uni drivers

            I did a rough estimate of measuring the delay by turning on Monitoring for my mic, snapping my finger and recording it in audacity, and then editing it so there were 2 successive snaps with the same delay I hear in my headphones. It worked out to be roughly 100ms.

            Apparently you’re supposed to be able to see other devices in the control panel but it looks to be a driver specific thing. If I could get that to work there would be almost no latency.

              As far as I know, it’s not possible to monitor inputs on Xonar cards under Windows without added latency. One reason I still have a Creative card in my PC as well – I use my PC for playing guitar and it’s just not possible with Xonar. Drivers don’t matter, Asus or Unified, there’s always delay.

              The only way to get a zero latency input monitor on Xonar I’ve found is to use Linux…

    Sometimes with opening any video in chrome, any video game,windows sounds, happens that loud white noise(so strange because my volume is about 56%).
    os:Win10 creators update.soundcard: Xonar DX
    driverversion:UNi Xonar W10 1825 v1.81a r2 driver , gonna try v1.80a r3

      I have the exact same problem with my Xonar DX. Doesn’t matter which driver I use (also ASUS stock drivers), it happens now and then. Usually I have my volume at 20%, so it kinda gives me a heartattack everytime it happens…

    Any eta when the planning of drivers will get updated?

      Please check FAQ Q&A 13. Currently there are no new audio drivers available from C-Media. To be honest, I don’t know if there will be any new audio drivers since audio card manufacturers shifted their attention to newer audio chips (not necessarily better) that have different drivers.
      But I am planing on updating all the UNi Xonar driver packages with the two new improvements I’ve discovered (SpeakerCompensation and Microphone Volume Increase by 3dB tweaks) and with improvements to the UNi Xonar installer. I don’t have any ETA on that.

    Since a couple of days, the audio regularly stops working after using windows for a while only fixable by a reboot, some games even cause BSODs just minutes after starting (DRIVER_IRQL_NOT_LESS_OR_EQUAL caused by cmudaxp.sys or STXII.sys).

    I tried the different driver versions and even reinstalled Windows 10 completely and tried all driver versions again, both issues persist. Did Microsoft release some update that broke the driver or could my STXII be broken?

      Well – since the card stopped working even under Linux I think it’s a hardware fault. I’m getting a replacement and will let you guys know if it fixes the issues.

        If you still have the card you should check the card in another PC so you know it’s the card and not a problem with the motherboard.

          Just replaced it, bluescreens fixed, never had a sound card “break” like that.

    I have a Xonar DX and have been on the 1.80 drivers for a while. I recently noticed that I couldn’t change the speaker input from 2 channels to 6, it was on 2 and would flick back to 2 the instance I selected 6.

    Anyway, I decided to try the 1.81 drivers. A bunch of BSODs and uninstalls/reinstalls later I’m back to 1.80 but cannot get the sound working. Specifically it no longer lets me change the input channels at all. It’s just blank and reselects to blank every time I try to select anything else. Where are the settings stored? Is there a way to force the number of channels? Is that a symptom of another issue? What call is being made during the selection process that could cause this behaviour?

    I’m hoping your can point me at a file I can hack to fix the issue.

      Have you tried C-Media Audio Panel or XonarSwitch? Do they have the same behavior? The issue could be caused by some newly released Windows update.
      The number of channels is a Windows setting, you can manually change it by going to Windows Volume tray icon->right-click->Playback devices->1 click on Speakers Asus Xonar(…) and press “Configure” button on the bottom left of the window.

        Yes the same behaviour. Originally I was using both C-Media Panel and I had a couple of profiles in XonarSwitch. I noticed the profiles weren’t being applied, so tried in C-Media Panel. This is when I did the Upgrade/BSOD/downgrade/etc. Since then I can still change everything except the number of channels in the C-Media Panel, but the windows configure button is non-responsive and I can’t change any of the xonar properties through windows settings (as in it wont bring up the menus or in the properties window I have two tabs (should be more), selecting the second tab I see a blank page. I can’t really interact with the windows sound settings at all really, it also wont let me set change/set the default device to a working one. I have to disable the Xonar in device manager to force it to change.

    No subwoofer in Win 10 Creator’s update with ASUS Xonar DSX PCIe 7.1 GX2.5 . Test from sound control panel applet works, also test from mixer. However, no bass from games and surround sound test apps. Same problem with built-in Realtek AC1150 (which is why I just bought the ASUS Xonar card.)

    I’ve found the root of the issue for the bug I mentioned in this post: http://maxedtech.com/asus-xonar-unified-drivers/comment-page-189/#comment-128503

    The problem is that XonarSwitch sets an incorrect value for the InputMicVolL subkey in “HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4D36E96C-E325-11CE-BFC1-08002BE10318}\0000\Settings”, when it tries to set 100% Mic Volume. It sets the REG_BINARY Data to “f2 12 fe ff”, which pans the Mic slightly to the right, when it should be setting it to “00 00 00 00” to match InputMicVolR and giving 100% Mic Volume panned to center.

    I know that it’s XonarSwitch, which you don’t develop. But is there any way you could pass the would along to the dev and he could do a quick update, since it is likely a very easy fix, being that it is only one registry value? If not, I understand. Thanks either way

      I will let Giulio know about microphone issue.

      In your linked post you’ve also mentioned about having the loud white noise and since you are testing the SpeakerCompensation tweak, I am curious if in your case the loud white noise still happens after you’ve disabled SpeakerCompensation. You can let me know in a reply to this comment.
